Negitive Feedback in Analog IC Design 02 April 2020 Javed G S, PhD
The webinar discusses the topics of negative feedback and its importance across the Analog IC design spectrum. In the talk, we discuss about the variations of feedback (Shunt and Series combinations) and their usage. It has applications in many control circuit design for power management, reference designs, regulator design, noise reduction in the system, gain desensitization and PLL design among many other systems.
And the end of the talk, the audience is expected to understand the need for the feedback and its applications
The term amplifier refers to any device that increases the amplitude of a signal, usually measured in voltage or current. This versatile device is used in a variety of different electronic applications. Especially in audio technology, a wide range of amplifiers can be produced based on product specifications (i.e. power, voltage, current). Currently, there are many types of audio amplifiers available for consumers. Sound signal amplification is used for instruments, such as the guitar or the bass. They are also used commonly in home theater systems and with stereo speakers. The basic design behind all of these amplifiers is derived from the simplest concepts of circuit design.
For our project, we set out to design an audio amplifier. The inputs of our circuit were stereo signals from a portable music player. Although we used a low-power speaker, we needed to achieve approximately three times gain over the entire circuit. In addition, the amplifier had to be produced at a low cost with available materials. Before building the actual amplifier, we realized that we had to design, simulate, and test the circuit. Each step was necessary to understand the concepts involved in amplification
Most physical systems incorporate some form of feedback. It is in.docxmoirarandell
“Most physical systems incorporate some form of feedback. It is interesting to note, though,
that the theory of negative feedback has been developed by electronics engineers. In his
search for methods for the design of amplifiers with stable gain for use in telephone
repeaters, Harold Black, an electronics engineer with the Western Electric Company,
invented the feedback amplifier in 1928. Since then the technique has been so widely used
that it is almost impossible to think of electronic circuits without some form of feedback,
either implicit or explicit. Furthermore, the concept of feedback and its associated theory
are currently used in areas other than engineering, such as in the modeling of biological systems.
Feedback can be either negative (degenerative) or positive (regenerative). In amplifier
design, negative feedback is applied to effect one or more of the following properties:
1. Desensitize the gain: that is, make the value of the gain less sensitive to variations in the values of circuit components, such as might be caused by changes in temper-ature.
2. Reduce nonlinear distortion: that is, make the output proportional to the input (in other words, make the gain constant, independent of signal level).
3. Reduce the effect of noise: that is, minimize the contribution to the output of unwanted electric signals generated, either by the circuit components themselves, or by
extraneous interference.
4. Control the input and output resistances: that is, raise or lower the input and output resistances by the selection of an appropriate feedback topology.
5. Extend the bandwidth of the amplifier.
All of the desirable properties above are obtained at the expense of a reduction in gain. It will be shown that the gain-reduction factor, called the amount of feedback, is the factor by which the circuit is desensitized, by which the input resistance of a voltage amplifier is increased, by which the bandwidth is extended, and so on. In short, the basic idea of negative feedback is to trade off gain for other desirable properties. This chapter is devoted to
the study of negative-feedback amplifiers: their analysis, design, and characteristics.
Under certain conditions, the negative feedback in an amplifier can become positive and of
such a magnitude as to cause oscillation. In fact, in Chapter 17 we will study the use of positive
feedback in the design of oscillators and bistable circuits. Here, in this chapter, however, we
are interested in the design of stable amplifiers. We shall therefore study the stability prob-
lem of negative-feedback amplifiers and their potential for oscillation.
It should not be implied, however, that positive feedback always leads to instability. In
fact, positive feedback is quite useful in a number of nonregenerative applications, such as
the design of active filters.
Before we begin our study of negative feedback, we wish to remind the reader that we
have already encountered neg ...

Block diagram of a typical op-amp – characteristics of ideal and practical op-amp - parameters of opamp – inverting and non-inverting amplifier configurations - frequency response - circuit stability.
A voltage amplifier circuit is a circuit that amplifies the input voltage to a higher voltage. So, for example, if we input 1V into the circuit, we can get 10V as output if we set the circuit for a gain of 10. Voltage amplifiers, many times, are built with op amp circuits.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
